Federal workers compensation statutes apply to which one of the following workers?

Federal workers' compensation statutes are designed to provide coverage for specific categories of workers engaged in federal or interstate business activities. One key group included under these statutes is interstate railroad workers. The Federal Employers Liability Act (FELA), for instance, is a federal law that provides compensation to railroad workers who are injured on the job, indicating that workers in this field have specific eligibility for federal compensation programs.

On the other hand, intrastate truck drivers operate within state lines and are typically covered under state workers' compensation laws, not federal statutes. Seasonal agricultural workers, while important, generally fall into state jurisdiction for workers' compensation as well. Private contractors, depending on their work context, are not necessarily covered by federal workers' compensation unless their work is directly tied to federal activities.

Thus, interstate railroad workers stand out as the correct answer since they are explicitly covered under federal workers' compensation laws, highlighting their unique status in the workers' compensation framework.
